SAW-HAN DLE.

SPECIFICATION forming part of Letters Patent No. 635,973, dated October 31, 1899.

Application filed Tute 3, 1899. Serial No. 719.268. (No model.)

tively inexpensive handle possessing great strength and durability and adapted to be readily applied to and removed from a sawblade.

A further object of the invention is to provide a handle of this character which will not become loose or separat-ed from a saw-blade through any shrinkage of the wood of. which the body portion of the handle is constructed.

The invention consists in the construction and :novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a longitudinal sectional View of a saw-handle constructed in accordance with this invention and shown applied to a saw-blade. Fig. 2is a longitudinal sectional View taken at right angles to Fig. l. Fig. 3 is a detail perspective view of the nut. Fig. 4 is a similar view of the yoke-bar. Fig. 5 is a detail sectional view of the handle.

Like numerals of reference designate corresponding parts in all the figures of the drawlugs.

l designates a wooden saw-handle having its inner end 2 reduced to receive a ferrule 3 and provided with a socket 4, in which is arranged a nut 5 for engagingV a threaded end 6 of a yoke-bar '7. The nut 5, which is cylindrical, terminates short of the outer end of the socket, as clearly illustrated in Figs. l and 2 of the accompanying drawings, and is provided with opposite wings or iianges 8, ex-

tending outward from a point opposite its center and terminating at the outer end of the socket. The longitudinal wings or flanges 8, which iit in slots 9 of the handle, are tapering, as shown, to form wedges, which have their reduced portions arranged at the side of the nut, whereby when the nut is forced into position the wedge-shaped wings or iianges will expand the slotted portion of the handle and coniine the saine in a tapering or flared portion l0 of the ferrule. The ferrule, which is provided with a cylindrical inner portion l1, has its outer portion l0 fiared or conical, as clearly shown in Figs. l and 2 of the drawings, and when the parts are assembled and the slotted end of the handle expanded there is no liability of the handle being pulled out of the socket while the saw is being operated.

The socket of the handle is not slotted throughout its entire length, and the wings or iianges by terminating at their inner ends at points opposite the center of the nut avoids weakening the handle to the extent of slotting it the entire length of the socket. The slotted portion, which is arranged within the conical or tapered portion of the ferrule, is expanded, and the handle is practically solid opposite the inner cylindrical portion of the ferrule. The ferrule is provided at its outer end with an inwardly-extending annular iange l2,hav ing a dished or inwardly-inclined outer face to t and form a seat for aY tapering washer 13, which is adapted to engage a saw-blade 14 and which has a flat outer engaging face. The washer is arranged on the yoke-bar 7, which has a threaded inner or upper portion 6 to be engaged by the nut, and by rotating the handle the washer is carried into engagement with the saw-blade, which is received within the slot l5 Vof the yoke-bar. By this construction the handle will be readily and quickly applied to and removed from a sawblade, and the washer will prevent the parts from sticking or binding in releasing the said blade.

The yoke-bar is provided between the ends of the slot with a bulged portion 16, forming an enlargement and operating as a stop to prevent the Washer from dropping o of the yoke-bar after the handle has been removed from the saw-blade.

The invention has the following advantages: The saw-handle, which is simple and comparatively inexpensive in construction, is strong and durable and is adapted to be quickly applied to and removed from a saw- IOO blade, and when the parts are assembled the slotted portion of the handle is extended within a conical or tapered portion of the ferrule, so that it is impossible for the handle to pull ont during the operation of the saw. The expansion of the slotted end of the handle also prevents the handle from loosening up after it becomes seasoned, and as the Wings or lianges terminate short of the inner ends of the nut the handle is not weakened by slotting the socket portion its entire length. The saw-handle is adapted to engage wide and narrow blades, and the washer prevents the blade from cutting into the fcrrule or binding. The enlargement which is located at the slot or opening of the yoke-bar prevents the washer from dropping off the saine when the handle is removed from the saw-blade.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departingr from the spirit or sacrificing any of the advantages of this invention.

Vhat is claimed isl. A device of the class described comprisl ing a handle having a socket and provided with a longitudinal slot extending through the wall of the socket, a ferrule arranged on the handle, and a nut arranged within the socket and provided with a longitudinallytapering wing or iange forming a Wedge and fitting in the slot of the handle, whereby the latter is expanded within the ferrule, and the nut is locked against rotation, substantially as described.

2. A device of the class described comprising a handle, provided with a socket and having slots, a ferrnle arranged on the handle and provided with a tapering or conical portion, a nut fitting in the socket and having tapering or wedge-shaped wings or llangcs fitting in the slots and expanding the handle within the tapering or conical portion of the ferrule, and a yoke-bar adapted to be engaged by the nut, substantially as described.

In testimony that I claim the foregoing as my own I have hereto allixed mysignature in the presence of two witnesses.
